I don't know what exactly is the term for that thing but here's how it happens:

Sometimes when you peel off stick tapes from a smooth surface, it leaves a grossy sticky layer. It's impossible to rub it off with wet wipes, even impossible to scrub off with nails or knife (yes, I've tried that a LOT and decide to give up).

I've got quite a few boxes and cards with that problem. When the marks are new they are extremely sticky you can't put them together with other cards or boxes, otherwise they all stick together. And if you leave them alone, very soon they'll attract a lot of dust and dirts, and wherever they are just go black.

They got me obssessed but I just don't know what to do with them. So annoying.

Anyone may know how to deal with such things?
